Storage and disk partitioning

  • You can run lsblk and blkid in the terminal to identify block devices

Hardware testing

  • You can run memtest86 from the boot menu if you are booting in BIOS/Legacy mode. This is not available if you are booting in UEFI mode.
  • You can run the memtester command in a terminal if you want to test your system memory. This command runs from the Linux system and hence is available if you run in UEFI mode. Make sure you run the 64bit version if your computer has more than 4GB of RAM so it can address all your memory.
  • The stress commmand can be used from a terminal in order to stress tests your system (CPU, memory, I/O, disks)
